Cytology microscope cover glass

borosilicate glassplainsoda lime

Product Description
Medical cover glass (microscope cover slips) are thin, flat sheets of optical-grade glass used to cover specimens on microscope slides. They stabilize and protect samples from contamination and damage while ensuring optimal optical clarity for routine and advanced microscopic analysis in clinical and laboratory environments.

Description
Flat, transparent optical-grade glass placed over a mounted specimen to hold it in position, protect against drying or contamination, and set the correct focal height for microscopy. Compatible with stains, dyes and common laboratory reagents. Available in multiple sizes and thicknesses to match objectives and specimen types.

Advantages

• Improved image quality: high light transmission and low distortion for accurate observation.
• Specimen protection: prevents contamination, drying and mechanical damage.
• Enhanced stability: keeps samples in place during manipulation and examination.
• Ease of use: simple handling and placement for efficient slide preparation.
• Compatibility with stains and fluorescence: suitable for many staining protocols and UV-transmissive options for fluorescence microscopy.
• Wide application: suitable for diagnostics, histology, cytology, pathology and general laboratory use.

Features

• Optical-grade glass: borosilicate or soda-lime options for clarity and chemical stability.
• Uniform thickness: typically ~0.13 mm (range 0.13–0.17 mm) for consistent focusing.
• Chemically inert surface: compatible with common reagents and staining protocols.
• Anti-reflective and UV-transmissive options: available for contrast improvement and fluorescence applications.
• Smooth, defect-free surface and optional polished edges to reduce chipping.
• Standard square and rectangular sizes to match laboratory needs.

Specification
